Is this enough?

Here is the dump output, followed by stack traces at the resize and remove
points (the remove goes on to fail).  The edge being split is:

(gdb) p *e
$9 = {
  src = 0x425cc8d0, 
  dest = 0x425cc8a0, 
  insns = {
    r = 0x425ccc90, 
    t = 0x425ccc90
  }, 
  aux = 0x424a1270, 
  goto_locus = 0x0, 
  flags = 0, 
  probability = 0, 
  count = 0, 
  dest_idx = 1111565824
}

Its src is:

(gdb) p *(e->src)
$12 = {
  stmt_list = 0x425cd7e0, 
  preds = 0x425bd7e0, 
  succs = 0x0, 
  aux = 0x0, 
  loop_father = 0x0, 
  dom = {0x1, 0x2710}, 
  prev_bb = 0x0, 
  next_bb = 0x0, 
  il = {
    rtl = 0x2
  }, 
  phi_nodes = 0x0, 
  predictions = 0x0, 
  count = 4781934674863446560, 
  index = 0, 
  loop_depth = 0, 
  frequency = 0, 
  flags = 1
}

Its dest is:

(gdb) p *(e->dest)
$13 = {
  stmt_list = 0x425cd780, 
  preds = 0x425bd7e0, 
  succs = 0x0,

  loop_father = 0x0, 
  dom = {0x1, 0x2710},

  }, 
  phi_nodes = 0x0,

  count = 4781934262546585568, 
  index = 0,

  frequency = 0, 
  flags = 1
}

Here is the dump:
